ORCHARD-HEATER..

Specification of Letters Patent,

Application filed January 10, 1910, Serial No. 537,278.

To all whom it may concern:

Be it known that I, PERCIVAL HAMMER TROUTMAN, a oltizen of theUnited-States,

- residing at Canon City, county of Fremont,

and State of Colorado, have'invented certain new and useful Improvementsin Orchard- Heaters; and Ido declare the, following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which'it appertains to make and use the same,reference being had to the ac-- companying drawings, and to the lettersand figures of reference marked thereon, which form apart of thisspecification.

My invention relates to improvements in orchard heaters, my object.being to providea construction of this class which shall be adapted toproperly perform the function indicated by its title. These heaterswhenin use are distributed through-the area covered'by, the orchard or wherethe vegetation to be protected is located, the number being sufficientto properly raise the temperature of the atmosphere over the entire areato be protected, to the degree necessary to prevent injury to vegetationdue to frost or the loweringof the temperature to a point which willinjure the same.

In my improved construction the fuel'receptacle hasa chimney located inits central portion and registering with an opening in the bottomthereof. This chimney is surrounded by a depending member adapted tolimit the volume of the combustion chamber or the portion of thereceptacle in which combustion actually takes place. This dependingmember is connected with a hood which itself either rests upon supportswith which the upper portionof the receptacle is provided, whereby thehood is raised above the receptacle to permit the entrance of air; orthe hood is corrugated, whereby it is adapted to rest directly upon theupper edge of the receptacle, the corrugations forming openings for theadmission of the necessary air for purposes of combustion.- The por-'tion of the dependingmember, extending 1 above the level of the fuel, isperforated, which is also true of the upper portion of the centrallylocated chimney. Having briefly outlined my improved construction, Iwill proceed to describe the same in detail, reference being made to theaccompanying drawing in which is illustrated an embodiment thereof.

In this drawing: Figure 1 is a central'verbustion purposes.

tic'al section of my improved orchard heater; Fig.2 1s a fragmentaryView of the upper portion of the same. Fig.3is a detail view partlybroken away, showing the hood and the depending member. Fig. 4: is asimilar Patented-Dec.13, 1910,

viewshowing a slightly modified form of construction The samereference,- characters indicate the same=parts in all the views.

Let the numeral 5 designate the fuel receptaclewhich is adapted tohold'oil 6 or other liquid fuel. This receptacle is supported upon acylindrical base 7 having a draft .openingf8 communicating with thechnnney 9 which is centrally located within" the receptacle. The-, upperpart' of this chimney is perforated 'as' shown at 10.

'As shown in Fig. 1 of the drawing, the upper portion of the receptacleis rovided with members 11 which project a ove the upper edge of therece tacle and form a support for a frusto-con1cal'hood 12 whoseupperedge is interlocked as shown at 13 with the upper extremit of thedepending member 1a which exten s downwardly into the fuel of thereceptacle the desired or necessary distance. As shown in the drawing,this depending member extends nearlyto the bottom of the receptaclewhile its upper project above the upper edge of the receptacle and forma support for the hood but when thrown to its other extreme position itwill not protrude above the edge of the receptacle but will allow thehood to completely close the same. This form of conportion is perforatedas shown at 15. The support 11 may consist of a member eccen-- tricallypivoted to the upper portion of the. fuel receptacle so that whendesired it may;

struction is illustrated in Fig.2 in which the support consists of adisk 16 eccentrically pivoted as shown at 17 the said disk beingprovided with a lug or projection 18 to reinforce the portion of itsedge which engages the hood when the disk is adjusted to support thehood above the top of the receptacle.

In the form of construction shown in Fig. 4, thehood is corrugated asshown at 19, whereby it may.rest directly upon the upper edge of thereceptacle, since by virtue of the corrugations ample provision is madefor the entrance of the necessary air for-com- Vhen the device is in usethe receptacle is provided with the necessary quantity of 011 which islighted within the space or area between the chimney 9 and the dependingmember 14. This space forms the combustion chamber of the heater, theoil being of course at the same level within the said fuel receptaclehaving a draft opening 1n the bottom thereof, a centrallylocat edchimney communicating with the said draft opening, a hood supported asuitable distance above the upper edge of the receptacle to form an airopening bet-ween the hood and the receptacle, the said hood having anopen ing therein, :1 depending member supported by the hood andcommunicating with the said opening the upper portion of the de pendingmember below the hood being perforated, the said member surrounding thechimney and suitably spaced therefrom to form a combustion chamberbetween the chimney and the receptacle, substantially as described.

2. An orchardll'lieater comprising- ,a fuel receptacle having a draftopening in the bottom thereof, an open ended chimney com'- municatingwith the said opening and extending upwardly through the receptacle, a

hood su ported over the upper edge of the receptac e, and having a spacebetween the hood and the edge of the receptacle to permit the-entranceof air for combustion, the

hood having an opening therein, a depending' member supported bythe'hood and in communication with the said opening the upper portion ofthe depending member below the 'hood being perforated, the said membersurrounding the chimney and suitably spaced therefrom to form acombustion chamber, substantially as described.

3. An-orchard heater comprising a liquid fuel receptacle having a draftopening in the bottom thereof, a centrally located open ended chimney incommunication with said draft opening, the upper portion of the saidchimney being perforated, a hood supported a suitable distance above theupper edge of the receptacle; to form an airspace between the-hood andthe receptacle-, the said hood having an opening therein, a dependingmember supported by the hood and in communication with theopeningtherein the upper portion of the depen din member below the hood beingperforated, the said member extending downwardly around the chimney intotheliquid fuel, andsuitably spaced from the chimney to form-a combustionchamber, substantially as described. p

4:..An'orcha'1d heater comprising a liquid fuel receptacle having adraft opening in the bottom thereof, an. ope ended chimney incommunication with the said draftopening, and extending upwardly throughthe receptacle, the upper portion of the said chimney beingperforatedforfeeding air to the'inner surface of the fuel, a hoodsupportedasuit-., able distance above theupper edge of the receptacle toform an air space between the hood and the receptacle, the said hoodhavmg an openln ber' supported the hood and in communication withtheopening therein the upper portion of the depending member below thehood being perforated, the said member ex-' tending downwardly into thefuel of thereceptacle and terminating a suitable distance above thebottom of the receptacle to permit of the entrance of the fuel into the.sai member, substantially as described.

In testimony whereof I atfix my signature in presence of two witnesses.
